Abstract

A disc brake arrangement (350) is provided as adapted for a wind turbine generator (300) incorporating a rotor shaft (320) supporting a rotor wheel and support ring (345) for a rotor structure (365) surrounded by a stator structure (315) within a generator casing (310). The disc brake arrangement (350) includes a brake disc (355) mounted normal to and concentric with the rotor shaft (320) and operatively connected to a support ring arm (346). A plurality of disc brake calipers (375) are arranged concentrically with the rotor shaft (320) and adapted to engage the brake disc (355).
